  5. ARB Session Outline DCR similar format to FCR, different focus: Less time for OCD, Prototype More time for Architecture, Plans General rule on focus: emphasize your projects high risk areas At FCR (in most cases) this will involve establishing the operational concept (including system analysis) At DCR (in most cases) this will involve the system design and development plan (especially schedule) (c) 2000-2009 5

  6. ARB Review Success Criteria (c) 2000-2009 4

  7. Development Commitment Review (DCR) More formal, with everything appropriate specifically tracing upward and downward No major unresolved issues or items, and closure mechanisms identified for any unresolved issues or items No more TBD's There should no longer be any "possible" or "potential" elements (e.g., Entities, Components, …) Persistant Information Classes with proper multiplicities No more superfluous, unreferenced items: each element (e.g., Entities, Components, …) either should reference, or be referenced by another element. Items that are not referenced should be eliminated, or documented as irrelevant (c) 2000-2009 7

  8. DCR ARB Session Overview Less time for OCD, Prototype More time for Architecture, Plan Fine-tuning based on FCR ARB experience Focus on changes since FCR Emphasize material that is relevant to 577B (or to end of class) Risk management still fundamental (c) 2000-2009 8

  9. ARB Chartsmanship & Presentation • Do not repeat the EPG or LeanMBASE Guidelines • Do not sweat the small stuff • Use audience-based terminology • NEVER read a slide’s contents • Paraphrase or hit only the high points • Practice, so it flows well, BEFORE your dry run • Assume 2 minutes presentation time per chart • After timed dry run practice • Don’t repeat previous speakers’ material • OK to refer to it • Do dry runs with at least one outsider (c) 2000-2009 9

  10. DCR ARB DCR ARB Session Outline (x,y): (presentation time, total time) (5, 5) Acceptance Test Plan and Cases; Team's strong and weak points + Shaping & Overall Project Evaluation (DEN Remote Team member) (5, 5) OCD.

  25. Quality Management Plan Describes plans for certain types of effort which increase the likelihood that the system will satisfy stakeholders’ win conditions • Writing code so that it’s readable, it contains certain useful information, and it avoids certain errors Coding Guidelines • Using peer reviews to catch defects early Peer Reviews (coordinate with Peer Review Plan) • Seeing that all requirements are verified, in an appropriate way Requirement Verification Testing strategies and levels • Ensuring that software changes are as agreed to by stakeholders and are as planned • Describes plans for managing the testing process: What kinds of tests (5) with level/kind of documentation • Identifies Configuration Management & CM system • Specifies project's Change Management?
